Unit1
Helping
those
in
need语法：不定式知识点详解
一、温故而知新：辨析谓语动词VS非谓语动词
1.谓语动词：顾名思义，在句中充当谓语，形式与句子时态相关。
例如：一般现在时态，谓语动词有原形和三单两种形式。
He
gets
up
at
5:00
o’clock
every
day.
一般过去时态，谓语动词形式为过去式。
We
went
to
Hong
Kong
last
summer.
2.非谓语动词：是相对于谓语动词而言的，非谓语动词不担任谓语成分,且具有其他词类特征的动词形式，即不定式，动名词和分词（现在分词和过去分词）。
例如：My
teacher
told
me
not
to
make
noise
in
class.
Watching
movies
help
me
learn
English.
The
man
standing
under
the
tree
is
my
father.
I
had
my
hair
cut
yesterday.
二、新知识点传授：非谓语动词不定式
1.动词不定式的结构：
肯定形式：
to
+动词原形。
否定形式：
not+
to
+动词原形。
2.动词不定式的用法
（1）作主语
例句：
To
learn
English
is
important.
=It
is
important
to
learn
English.
To
walk
to
school
takes
me
20
minutes.
=It
takes
me
20
minutes
to
walk
to
school.
注意：在It
is…
to…”的句型中，it是形式主语，真正的主语是不定式,使用这种结构,可以避免句子的头重脚轻。通常不定式被视为第三人称单数，所以谓语动词用单数。
【练习1】It’s
a
good
habit_____（take）a
walk
after
dinner.
It作形式主语常见结构：
▲
“It
is
+
adj./n+(for

lend
him
money

do
一感
feel/
二听
hear,
listen
to/
三让
let,
make,
have/
四看
look
at,
see,
watch,
notice
B.
it做形式宾语代替不定式,
常见结构有
find/
think/
make...+
it
+adj.+
(for
sb.)
to
do
sth.（初二学生可做拓展）
